Add SchedulerGWS debug variable

- SchedulerGWS forces gws for scheduler kernel - useful when using
TBX server
- Fix misaligned scattered write in scheduler kernel when
SchedulerSimulationReturnInstance is set to value > 1
- Fix copy_test_files dependecy - modification of files in test_files
triggers copy_test_files targets
